The local SYK model and its triple scaling limit
Takanori Anegawa, Norihiro Iizuka, Sunil Kumar Sake
We study a model of fermions with random couplings similar to conventional SYK with number of flavours of fermions, at large . Unlike the conventional SYK model, which has a…
Sparse random matrices and Gaussian ensembles with varying randomness
Takanori Anegawa, Norihiro Iizuka, Arkaprava Mukherjee +2
We study a system of qubits with a random Hamiltonian obtained by drawing coupling constants from Gaussian distributions in various ways. This results in a rich class of system…
Shock waves and delay of hyperfast growth in de Sitter complexity
Takanori Anegawa, Norihiro Iizuka
We study the holographic complexity in de Sitter spacetime, especially how the hyperfast growth of holographic complexity in de Sitter spacetime is affected under a small and early…
Late time behavior of -point spectral form factors in Airy and JT gravities
Takanori Anegawa, Norihiro Iizuka, Kazumi Okuyama +1
We study the late time behavior of -point spectral form factors (SFFs) in two-dimensional Witten-Kontsevich topological gravity, which includes both Airy and JT gravities as spe…
Is Action Complexity better for de Sitter space in Jackiw-Teitelboim gravity?
Takanori Anegawa, Norihiro Iizuka, Sunil Kumar Sake +1
Volume complexity in dS remains up to a critical time, after which it suddenly diverges. On the other hand, for the dS solution in JT gravity there is a linear dilat…
